More than a decade ago, photography experienced a technological shift with the proliferation of digital cameras. As photographers embraced digital cameras, their desire to access low-level image data increased, resulting in the increase of RAW file formats and workflows. Unfortunately, the digital still image raw workflow brought with it a slew of file formats (over 200 for still cameras!) that are proprietary, closed, and sometimes even encrypted.
Today, the cinema industry is experiencing a similar transition as many filmmakers are foregoing film in favor of digital cinema cameras and workflows. Digital cinema cameras have led to an increasing trend in the usage of RAW workflows and proprietary RAW formats. Proprietary raw formats lock participants, both vendors and users, into walled gardens with limited interoperability and longevity.
First published in 2009, the CinemaDNG specification established an open raw cinema format upon which interoperable digital cinema workflows can be implemented. In 2011, Adobe officially turned over control and support of the CinemaDNG specification to a community of partners to ensure its future and encourage industry adoption. Adobe will continue to participate and provide input to the specification as a member of this community.
